Intel Core 3 100HL

Manufacturer: Intel

The Intel Core 3 100HL is a desktop processor built on a 10 nm process and designed for the LGA 1700 platform. It employs big.LITTLE technology to split workload across two sets of cores — four performance cores clocked at 2.1 GHz and four efficiency cores at 1.5 GHz — with a turbo frequency reaching up to 4.6 GHz. The chip supports multithreading, delivering 12 threads in total, and carries a thermal design power rating of 45 W.

On the memory side, the Core 3 100HL works with DDR5 RAM at speeds up to 5200 MHz across two channels, with a maximum supported capacity of 96 GB. Its integrated graphics engine features 48 execution units, a turbo clock of 1300 MHz, and compatibility with DirectX 12, OpenGL 4.6, and OpenCL 3, with support for up to four simultaneous displays. The processor scores 17899 in the multi-core PassMark benchmark and 3731 in the single-core test, and includes a broad instruction set covering AVX2, AES, FMA3, and SSE 4.2 among others. PCIe 4 connectivity and NX bit support round out the feature set.

Pros
  • Supports DDR5 memory at speeds up to 5200 MHz, keeping memory bandwidth in line with modern platform expectations
  • The integrated graphics engine covers DirectX 12, OpenGL 4.6, and OpenCL 3, enabling compatibility with a wide range of graphics and compute workloads without a discrete GPU
  • Up to four displays can be driven simultaneously through the integrated graphics unit
  • A maximum RAM capacity of 96 GB offers substantial headroom for memory-intensive tasks
  • The broad instruction set — including AVX2, FMA3, and AES — ensures compatibility with a wide range of modern software
  • big.LITTLE core arrangement allows workload distribution across performance and efficiency cores
Cons
  • The multiplier is locked, so there is no option to adjust clock speeds through overclocking
  • ECC memory is not supported, which limits suitability for use cases where data integrity is critical
  • The efficiency cores run at a base clock of just 1.5 GHz, which may limit responsiveness in certain multi-threaded scenarios
  • A 45W TDP may require adequate cooling solutions to maintain sustained performance within thermal limits
Who is this for?

This processor is a reasonable fit for everyday desktop computing tasks such as office productivity, web browsing, and light media consumption, where its big.LITTLE core architecture can distribute workloads efficiently between performance and efficiency cores. The integrated graphics unit with DirectX 12 support and the ability to drive up to four displays simultaneously make it a practical choice for multi-monitor office setups that do not rely on a discrete GPU. Users who need a platform supporting DDR5 memory up to 96 GB for moderately memory-intensive applications will also find this chip a workable option within the LGA 1700 ecosystem.

Who is this NOT for?

This processor is not well-suited for users who require overclocking capabilities, as the multiplier is locked and clock speed adjustments are off the table. Those working in environments where data reliability is paramount — such as servers or workstations handling critical data — will find the lack of ECC memory support a significant limitation. Similarly, users looking to run graphically demanding applications, modern games at higher settings, or GPU-accelerated creative workloads will likely find the integrated graphics unit insufficient for those needs.

Performance:

CPU speed 4 x 2.1 & 4 x 1.5 GHz
CPU threads 12 threads
turbo clock speed 4.6GHz
Has an unlocked multiplier ✕
L3 cache 12 MB
Uses big.LITTLE technology ✓
clock multiplier 21

The processor uses big.LITTLE technology to split its eight cores into two groups — four running at 2.1 GHz and four at 1.5 GHz — while a turbo clock speed of 4.6 GHz can be reached under boosted conditions. Across all cores, it provides 12 threads in total, supported by a clock multiplier of 21. A 12 MB L3 cache helps reduce memory latency during demanding workloads, though the multiplier is locked, meaning clock speed adjustments through overclocking are not available on this chip.
